It may holding the strip across the mouth of the also be formed as an attachment which will transmitter, and preferably a suitable tension device is provided at the side of the mouth of the transmitter opposite to the side from which the paper strip is fed'to slidably hold the strip across said mouth. For this purpose in the drawings 1 have shown a bearing dat the side of the transmitter-mouth 0pposite the side at which the paper-roll or other strip-supplying means is located, and said shielding -strip 1) extends across said mouth and behind said bearing. the bearing is rearward of the mouth of the transmitter, so that the shielding-strip will be drawn forward from the strip-supplying means, then bent down across in front of the mouth, and then back behind the bearing, thus holding the strip taut across the mouth of the transmitter. Suitable means are provided for holding said strip against said hearing to prevent any withdrawal of the strip by resiliency. 2 indicates a tension-roller for this purpose.

findicates a spring to throw the tensionroller 6 against the bearing (1. The hearing (I may be of any suitable form. When the bearing and tension device are rollers, as indicated in the drawings, the shielding-strip is gripped between said rollers.

g indicates an edge piece, against which the free end of the strip may be drawn in order to tear it from the body of the strip.

71 indicates a tablet over which the strip may be drawn and which forms a support for the strip, so that the users of the telephone may conveniently use the paper strip for the purpose of making memoranda thereon.

When the appliance is manufactured separately from the transmitter to be applied as an attachment to the transmitter, a clamp 'i is provided, and the strip-roller c or other means for supplying the shielding-strip to be drawn across the month of the transmitter and the means for holding the strip tight across the transmitter-mouth will be carried by said clamp.

In the drawings I have shown means in front of the transmitter-mouth for holding the strip against said mouth. Such means consist in a springpressed ring j, which is preferably the same diameter as the mouthpiece. The said ring is preferably pivoted to the clamp-frame and is pressed by a spring 70.

Zindicates a nut on the shaft-roller c,whereby the roller for holding the roll of paper is detachably attached to the clamp-frame.

In practical use the appliance will be furnished with a strip of paper placed on the roller, as indicated in the drawings, and the free end of the strip will be brought down in front of the mouthpiece or earpiece of the transmitter, and when the user desires to bring an unused portion of the paper across the mouth of the transmitter he will grasp the free end of the paper and draw it up against the edge piece g and will tear ofi a portion of the paper and throw it away or otherwise dispose of it. If he desires to make any memorand um on the paper,ho will do so before tear- Preferably ing it off, using the tablet h to support the paper against the pressure of the-pencil.

The ringj may be detached and dispensed with, if desired, thus to present to the user only the face of the strip in front of the transmitter-mouth.

The nut Z when screwed home holds the roller friction tight to prevent racing of the strip.

The strip pressing rollere and the roller 61, together with the strip-feeding appliance, holds the strip tant in front of the speech appliance a in the usual operation of the device; but the meansj, directly in front of the speech appliance, serves to hold the strip flat against the rim of said appliance to prevent buckling up ,in case the strip should become disengaged from the lower roller or should the upper roller be unreeled too much.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination with a sound-transmitter, of means at one side of the month of said transmitter for supplying a shielding-strip to be drawn across said mouth; means at the other side of said mouth for holding said strip across said mouth; and a tablet over which said strip may be drawn.

2. An attachment for sound-transmitters comprising a clamp to clamp upon the transmitter; means carried by said clamp for supplying a shielding-strip to be drawn across the mouth of the transmitter; and means carried by said clamp for holding the strip across the transmitter-mouth.

3. An attachmentfor sound-transmitters comprising a clamp to clamp upon the transmitter; means carried by said clamp for supplying a shielding-strip to be drawn across the mouth of said transmitter; a bearing for said strip; and a spring-pressed roller for holding said strip against said bearing.

4. Thecombination with a sound-transmitter, of a tearable strip; means for slidably holding said strip across the mouth of the transmitter; and a tablet to the rear of said strip and across which the strip may be drawn.

5. The combination with a sound-transmitter, of a tearable strip; means for slidably holding said strip across the mouth of the transmitter; an edge piece across which the free portion of the strip may be drawn to be torn; and a tablet to the rear of the strip and across which the strip may be drawn, said tablet being between the transmitter and the edge piece.

6. An attachment for speech appliance comprising means for engaging with said, appliance and provided with mechanism for holding a shielding-strip in front of theappliance, and means directly in front of the appliance for holding the strip against outward movement.

7. An attachment for speech appliance, comprising means for engaging with said appliance and provided with mechanism for holding a shielding-strip in front of the appli- IIO ance, and yielding means directly in front of the appliance for holding the strip against outward movement.

8. An attachment for speech appliance, comprising means for engaging with said appliance and provided with mechanism for holding a shielding-strip in front of the appliance, and a ring in front of the appliance for holding the strip against outward movement. v

9. An attachment for speech appliance, comprising means for engaging with said appliance and provided with mechanism for holding ashielding-strip in front of the appliance, and a ring yieldingly held in front of the appliance for holding the strip against outward movement.

10. An attachment for speech appliance, comprising means for engaging with said ap pliance and provided with mechanism for holding a shielding-strip in front of the appliance, and a ring hinged at one side in position to be swung in front of the attachment and hold the strip against outward movement.

11. An attachment for speech appliance,

comprising a frame for engaging with said appliance and provided with mechanism for holding a shielding-strip in front of the appliance, and a spring-pressed ring hinged to the frame in position to be swung over in front of the appliance'and hold the strip against outward movement.

'12. An attachment for speech appliance, comprising a frame for engaging with said appliance and provided with mechanism for holding a shielding-strip in front of the appliance, a tablet, and an armed ring hinged to the frame in position to be swung in front v of the appliance with the arms extending 0 across the tablet.

13. An attachment for speech appliance, comprising a frame for engaging with said appliance, a strip-roll at one end of the frame and clamping-rolls at the other, a tablet adjacent to the clamping-rollaand a ring hinged to the frame adjacent to said rolls in position to be swung across the tablet and lie in front of the appliance and prevent outward movementof the strip. 5o 14. An attachment for a speech appliance, comprising, means for engaging with said appliance and provided with mechanism for holding a shielding-strip taut in front of the appliance and means in front of the appliance for holding the strip against outer movement.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, California, this 18th. day of April, 1900.
